To all whom it may concern.-

Be it known that HENRY o. HoDGE a citizen of the United States, residing at Detroit, county of Wayne, State of -ll [ichigan, have invented a certain new and useful Improvementin Construction of Roofs, 8m. and

I declare the following to be a full, clear, and exact description of the same, such as will enable others skilled in the art to which it appertains to'make and use the same, reference 7 being had to the accompanying drawings, which form a part of this-specification; I

In-the drawings, Figure l is a View in perspective of a section of a roof construction embodying my invention. Fig. 2 is aview'of the joint wherbythe purlin, rafters, and roofing are united. Fig. 3 represents detail views of the parts constituting the said joint.

v Fig. 4 is a variation of, my invention. Fig. 5

is another'variation.

In the construction ofroo'fs, and especially those which are provided with metallic trusses, girders, and purlins, the said roofs are rendered exceedinglyexp'ensive, owing tothe la-' bor required in their construction. It is the purpose of my invention to make a roof con struction of this character which shall be at once substantial and inexpensiver A feature of large expense heretofore has been the joints whereby the roofing and purlins and the rafters are united. This Iaccomplish as follows: D is'ablockof metal, shaped upon its upper side for the reception of the said channeled or corrugated roofing. If the roofing is channeled or corrugated, as shown in the drawings, then the upper portion of this piece is shaped to fit the said channel or corrugation. The under side of the said piece D is providedwith a concave bearing for the purlin I propose to makeof metallic pipe. If,-h0wever, the purlin be .of any other form of metal, the cavity in the block Dshould be made to correspond thereto. -E is another block. This upon its upper side isconcaved 1 in a directionat right angles to the purlin for that this joint is tion.

usual variety of ways, and these will necessi tate corresponding fittings atth'e points where the braces meet.

Instead of employing bolts or nuts, the roofing and blocks, purlins, and rafters may be fastened together ,byany other convenient means-as, for instance, by any suitable clampi This peculiar joint is not limited solely 'for' roofing purposes, but is equallyapplicable wherever twoor more such elements are to be joined together substantially as the roof-plate, the purlins, and the raftersare here joined to gether. So, also, the bloeksmay be so grooved or shaped as to permit the pipe or pipes to cross the block at an angle other than a right angle, as shown in Fig. 4. It is also adapted for the connection directly of channe1edmetal,;
